See "Accessories" for the order number. - The file should cut only when pushed forwards (arrow). Lift the file when leading it backwards. - First sharpen the shortest cutter. The length of this cutter is then the standerd for all other cutters of the chain. - Always guide the file as in fig. shown 4/5 - The file holder makes file guidance easier. It is marked for the correct 30° sharpening angle (keep the marks parallel with the chain when filing, see illustration) and limits the cut depth to the correct 4/5 of the file diameter. See "Accessories" for the order number. 2 - After having sharpened the chain, the height of the depth limiter must be checked by means of a chain gauge.
